WINDMILL.

SPECIFICATION forming part of Letters Patent No. 485,082, dated October25, 1892. Application filed September 30, 1890. Serial No. 366.678. (Nomodel.)

To all whom it may concern.-

Beit known that I, EDWIN J. BARBER, a citizen of the United States,residing at Gove City, in the county of Gove and State of Kansas, haveinvented a new and useful Windmill, of which the following is aspecification.

The invention relates to improvements in windmills.

The object of the present invention is to provide a windmill of simpleand comparatively-inexpensive construction adapted to automaticallyregulate itself and close the sections of blades in case of heavy winds.

A further object of the invention is to pro-` vide means whereby thestroke of the pump- 'rod can be readily adjusted.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a side elevation of a windmill constructedin accordance with this invention. Fig. 2 is a central verticalsectional view. Fig. 3 is a similar view taken at right angles to Fig.2. Fig. 4 is a vertical sectional view on line of Fig. 2.

Referring to the accompanying drawings, 1 designates a tower, havingrotatably mounted therein a frame 2, composed of vertical beams 3,provided midwayv their length with a casting 1l, circular in shape andhaving a central rectangular opening to receive the frame and providedwith rollers 5, adapted to bear on the top of the tower and form aturn-table. The vertical beams 3 of the frame are spaced by blocks 6,arranged at their lower ends and at a point opposite the casting 4, andthe said lower ends of the beams 3 are provided with castings 7, mountedin suitable bearings in a cross-piece 8 of the tower 1 and adapted tosupport the lower end of the rotating frame.

J ournaled in suitable bearings 9 at the upper end of the frame 2 is amain shaft 10, extended beyond the sides of the frame and having one endcarryingawind-wheel 1l and the other end provided with a depending boltarranged to support avane 12,having its side bars rigidly secured to theframe and arranged parallel with and slightly below the main shaft 10.The main shaft communicates its motion to a pump-rod 13 by a pitman 14and an eccentric 15, and the latter is provided with a series ofopenings 16, arranged at various distances from the center and adaptedto regulate the length of the stroke of the pump-rod.

,The wind-wheel 11 is composed of a hub 17, radial spokes, preferablyconstructed of tubular metal, and hinged bladesl arranged in series orsections and having their outer ends connected by a bar v20, provided atits ends with journals 21, that are mounted in suitable bearings at theends of the spokes, and it. -will be seen that as the outer ends of thesections of blades 19 are hinged, increased winds, will tend to throwtheinner ends of the blades away from the center or hub of the wheel,thereby opening the blades and throwing the mill out of the wind andproducing an automatically regulated device. The blades 19 are slightlycurved and are secured near their outer ends to the bar 20, and aresimilarly secured at their inner ends to a bar 22, extended beyond thesections of blades upon both sides of the same and adapted to engage thespokes 18 of the wheel and prevent the blade swinging inward between thespokes toward the rotating frame. The center blade of a series hassecured to it one end of a horizontal rod 24, the other end of which isprovided with an eye that engages a similar eye at the lower end of avertical rod 25, extending from the horizontal rod to a sleeve or disk26. The sleeve or disk 26 slides upon the main shaft between the wheeland the frame and is adapted to open and close the hinged sections ofblades and throw the mill into and out of the wind, and it is featheredor splined to the main shaft and rotates with the wheel and is providedon its inner face with a flange 27, having a circumferential groove 2S,in which is arranged a ring 29,provided with lateral projections 30, towhich are secured diverging arms 31 of a hinged bar 32, connected by arod. 33 to one arm of a bell- Y crank lever 34, the other arm of whichis connected with the bottom of the tower to enable vvelocity of t-hewind-wheel,caused by violent ICO the wheel and the operation of the millto be controlled from below. The bell-crank lever is mounted in anopening in one of the beams 3 of the frame and has secured to its innerarm the upper end of a rod 3G, extending to the lower end of the frameand provided with tappets 37 arranged above and below a slide 38, havinga central opening 39 to receive the pump-rod 13, and provided withVextensions or ends 40, arranged to slide vertically in openings or ways4l in the beams 3, and the said slide has secured in its central openingthe upper end of a tube 42,which forms a guide for the pump-rod, and isprovided at its lower end with a grooved disk 46, having connected to itsuitable means Wherebythe slide maybe operated from the bottom of thetower. The rotation of the wheel will naturally open the sections ofblades and hold the mill out of the wind, and a suitable weight maybeconnected with the slide 38 to hold the blades into the wind andregulate the rotation of the wheel.

It will readily be seenthat windmills constructed in accordance withthis invention are simple and comparatively inexpensive in constructionand are capable of being antomatically regulated, and it will also beseen that the eccentric enables thelitt of the pumprod to be regulated.

The shaft l0 is extended beyond the frame in the direction of the vane,and extending upward from the vane is a rod 47,7which is provided at itsupper end with a bearing-eye 48 to receive the shaft, and by thisconstruction the vane is supported and the weight of the wheelcounterbalanced.

In a windmill, the combination of the tower l, a frame 2, with slots inthe lower part thereof and supporting a shaft having a wheel thereonwith adjustable blades and also having a vane attached thereto, apump-rod or plunger connected to said shaft of the Wheel, a tube 42,surrounding said pump-rod or plunger and having extensions secured tothe upper end thereof adjustably extending into said slots in the lowerpart of frame 2, one of said extensions having a vertical holetherethrough, a disk 46, connected to the lower part of the said tube 42to operate the latter, and a vertical rod 36, connected to the blades ofthe wheel and inovably extending through the said extension having theopening therein and provided with tappets 37, located above and belowsaid latter extension to operate the same, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
